application June 17 1948, Serial N 0. 33,461 '2 Claims. (Cl. 393) Thisinvention relates to turnstiles.

An object of this invention is to provide an improved turnstile formounting in a theater entrance, bus station or other location, which isreleased for operation by means of one or more coins of requireddenomination, and is automatically reset upon the passage of one person.

Another object of this invention i to provide in a turnstile an improvedcoin actuated release means embodying in one embodiment of thisinvention a spring-pressed latch release lever which is spring urged toeither locking or releasing position, being moved .to releasing positionby means of the inserted coin, and being moved to latched position underthe action of a cam which engages the latching pawl. In anotherembodiment of this invention the latching pawl is released electrically,and is held in either latched or released position by means of a camspring.

With the above and other objects in view, my invention consists in thearrangement, combination and details of construction disclosed in thedrawings and specification, and then more particularly pointed out inthe appended claims.

In the drawing,

Figure 1 is a fragmentary horizontal section of a passageway having aturnstile mounted therein constructed according to an embodiment of thisinvention,

Figure 2 is a fragmentary vertical section of the turnstile, 1

Figure 3 is a fragmentary vertical section on an enlarged scale of thecoin operated latching means,

Figure 4 is a fragmentary sectional view taken on the line 4 -4 ofFigure 3,

' the standard II]. The standard I has mounted therein a verticallydisposed shaft I4 on the upper end of which is mounted a turnstilestructure I5.

The turnstile structure I5 includes a plurality of divergent bars I6which are secured to a housing I'I fixed to the upper end of therotatable shaft I4. The housing I! includes a top plate I8 having one ormore coin slots I9 through which a coin 20 is adapted to be extended.The plate or disc I2 has fixed to the upper side thereof at least 4circumferentially spaced apart lugs or teeth 2I with one of which a dogor pawl 22 is adapted to be engaged. The pawl 22 is rockably carried bycars 33 depending from the bottom wall 24 of a receptacle 25 which isdisposed within .the housing IT.

The pawl 22 has pivotally secured thereto a vertically disposed link 26which engages through aguide 21 carried by the receptacle 25. The upperend of the link 26 is rockably connected to a coin actuated lever 28pivotally secured as at 29 to a boss 29a to the top wall I8. A spring 30which is secured at one end as at 3| to a bracket 3m fixed to the topwall I8, as at 3Ib, is connected with the lever 28 forwardly of thepivot 29 so that the spring 30 will hold the lever 28 in either an upperset position or in a lower pawl releasing position, shown in dottedlines. When the pawl 22 has been raised out of engagement with theadjacent tooth 2 I, the turnstile I5 may be rotated at least one-quarterturn, as shown in dotted lines, and at a point between adjacent pairs ofteeth 2| a re-setting cam 32 is disposed which is mounted on a support33 carried by the disc I2.

The pawl 22 has a cam engaging pin 34 fixed thereto which is adapted toengage the cam 32 upon rotation of the housing I'i so that the pawl 22will be lowered to a point where the spring 30 will move above thehorizontal centerof the pivot 29 and raise lever 28, and upon raising oflever 28 by spring 30, pawl 22 will be rocked downwardly to slidingengagement with disc I2 and in a position to abut against the nextadjacent tooth 2 I.

This turnstile has been designed particularly to provide a means wherebypatrons of theaters, buses or the like may enter the theater or busstation without first purchasing a ticket, the turnstile being designedto eliminate the purchase of tickets.

I do not mean to confine myself to the exact details of constructionherein disclosed but claim all variations falling within the purview ofthe appended claims.

What I claim is:

1. A coin operated turnstile comprising an upright standard, avertically disposed shaft rotatably carried by said standard, a housingfixed to said shaft, a toothed plate fixed to said standard and formingthe bottom wall of said housing, radial arms extending horizontally fromsaid housing, a pawl rockably carried by said housing engageable withthe teeth of said plate, a pawl operating lever rockably carried by saidhousing, a link connecting one end of said lever with said ,pawl, aspring connected with said lever in a manner to hold said lever ineither pawl released or latched position, and correlated means carriedby said plate and said pawl for rocking the latter downwardly tolatching position upon rotation of said housing.

2. A coin operated turnstile comprising an upright standard, avertically disposed shaft rotatably carried by said standard, a housingfixed to said shaft, a toothed plate fixed to said standard and formingthe bottom wall of said housing, radial arms extending horizontally fromsaid housing, a pawl rockably carried by said housing engageable withthe teeth of said plate, a pawl operating lever rockably carried by saidhousing, a link connecting one end of said lever with said pawl, aspring connected with said lever in a manner to hold said lever ineither pawl released or latched position, a stationary cam carried bysaid plate between each pair of teeth, and a cam engaging member carriedby said pawl engageable with an adjacent cam u'pon rotation of saidhousing for rocking said pawl downwardly to latching position.
